使用nginx部署daphne报AttributeError错误

在开发环境下websocket运行正常，使用nginx部署后，报错。
报错信息如下：

这是因为，在urllib3.AllowedHostsOriginValidator被破坏了。我解决了这个问题，编辑了我的asgi.py file.

application = ProtocolTypeRouter({
    "websocket": AllowedHostsOriginValidator(
        AuthMiddlewareStack(
            URLRouter(
                websocket_urlpatterns
            )
        )
    ) 
})
# 将上面代码改成
application = ProtocolTypeRouter({
    "websocket": AuthMiddlewareStack(
        URLRouter(
            websocket_urlpatterns
        ) 
    )
})
